Definitions
- a circular emission pattern is useful for circumferential illumination, while semicircular emission is particularly advantageous for waveguide injection, such as for exit signs, instrument displays and other similar implementations.
- Some preferred embodiments utilize profiles of faceted total-internal-reflection lenses.
- Totally internally reflecting (TIR) lenses such as those disclosed in U.S. Patent No. 5,404,869 by Parkyn, Pelka, and Popovich , and U.S. Patent Nos. 5,676,453 and 5,806,955 by Parkyn and Pelka , utilize faceted profiles as circularly swept around an axis parallel to the output beam, or linearly swept along a line perpendicular to the faceted profile.
- the present embodiments are designed in some implementations to be similar to design of traditional TIR lenses, and have a central lens, a section with Fresnel facets employing redirection by refraction only, and finally a section which employs TIR facets that redirect by a combination of refraction and TIR.
- the TIR facets can have faces that are either flat or can be curved as is desired. Some embodiments use curve facets to achieve a slightly higher collimation in the vertical direction than with the straight facets.
- Some present embodiments incorporate design considerations, such as those known by one skilled in the art of TIR lens designs, for circumferential TIR lenses such that the beam output can be varied to achieve a variety of performance goals. For example, with a given height of the lens and size of source the vertical beam spread can be adjusted up or down as,limited by the laws of nonimaging optics. The vertical spread can be adjusted for specific prescriptive goals by subtle adjustments of the shape and position of the central lens, Fresnel facets and TIR lenses.
- Circumferential illumination in the horizontal plane is desired, for example, with masthead lights on boats, with a ⁇ 7° beam of white light for powered boats and ⁇ 25° for sailboats and buoys, and other similar uses.
- High-powered white LEDs such as those sold by Lumileds, of San Jose, California, have enough lumens (10-20) to meet the requirements for one, two, and even three-mile lights when incorporated with the present embodiments.
- FIG. 7 shows one preferred embodiment for these applications.
- semi-circular transverse-axis lens 1500 is shown, incorporating asymmetric TIR lens profile 1501 in accordance with U.S. Application Serial No. 60/319,746 by Mina ⁇ o, Falicoff, Benitez, Parkyn, Chaves and Sun .
- Profile 1501 is swept 180° about vertical axis 1510 to form recessed faceted cavity 1502.
- the exterior surfaces of lens 1500 comprise right flat surface 1503, left flat surface 1504, conical bottom surface 1505, and bullet-shaped exit surface 1506, tailored in shape to adjust down-going rays 1520.
- Rays 1520 have the same downward angle inside lens 1500, but the shape of external surface 1506 gives them a distribution of angles downward, for illumination of a proximal horizontal surface.
